It is probable that most of these occur throughout the State ; but the ordi- 

 nary fate of a mosquito is not that of being carefully bottled or pinned : there- 

 fore our collections are not so good as they might be. 



Family CHIRONOMIDiE. 



These flies are indifferently named "gnats," "midges," "sand-flies" or 

 "punkies," the latter two names chiefly applied to the few minute forms 

 with piercing mouth parts. They resemble mosquitoes in appearance, but 

 have naked wings, and the thorax is produced so as to hide the small head 

 from above. The antennae in the male are lengthily plumose and in the female 

 are also furnished with lateral hair. The insects occur at all seasons, many of 

 them in spring, and they have the habit of dancing in the early evening in 

 great swarms only a few feet above ground, usually in a damp locality. The 

 larvae live in water on living or dead vegetation, or on sap of trees, under 

 fallen leaves or decaying vegetable matter. 



As a rule they are harmless, except for the annoyance caused by the biting 

 tribes, but the larva of one species at least mines the leaves of water plants 

 and thus becomes injurious in a very limited and special way.
